10. On a warm, sunny day, a student uses a tire pressure gauge to test the air pressure of her tires. While
listening to the weather report on the way to the garage, she finds that the barometric pressure is 780
mm Hg. If the gauge reads a pressure of 35 lb/in2, what is the actual pressure inside the tires? Please
give your answer in lb/in2, mm Hg, atmospheres, and Pascals.
